用Newtonsoft在C#中验证JSON和JSON Schema

using Newtonsoft.Json;
using Newtonsoft.Json.Schema;

// JSON数据
string jsonData = "{\"name\":\"John\",\"age\":30,\"city\":\"New York\"}";

// JSON Schema
string schemaJson = "{\"type\":\"object\",\"properties\":{\"name\":{\"type\":\"string\"},\"age\":{\"type\":\"integer\"},\"city\":{\"type\":\"string\"}},\"required\":[\"name\",\"age\"]}";

try
{
    // 将JSON字符串转换为C#对象
    var obj = JsonConvert.DeserializeObject(jsonData);

    // 解析JSON Schema
    var schema = JsonSchema.Parse(schemaJson);

    // 验证JSON数据是否符合JSON Schema
    IList<string> validationErrors;
    bool isValid = obj.IsValid(schema, out validationErrors);

    if (isValid)
    {
        Console.WriteLine("JSON数据有效");
    }
    else
    {
        Console.WriteLine("JSON数据无效");
        foreach (var error in validationErrors)
        {
            Console.WriteLine(error);
        }
    }
}
catch (JsonReaderException ex)
{
    Console.WriteLine("无效的JSON数据：" + ex.Message);
}
catch (JsonSchemaException ex)
{
    Console.WriteLine("无效的JSON Schema：" + ex.Message);
}
